LGV20 Not Booting, Internal Memory Recovery

Frowny

Hello,
While helping my mother move out her V20 stopped working with no apparent warning. The screen just turned black, and now the device will not start. Occasionally (after long enough for the battery to die or a boot to fail?) holding the power button will cause it to vibrate. The screen will briefly backlight to 'light black' every five inputs or so, with no apparent pattern.

This was all over a week ago and she's since replaced the phone, but I'm still trying to recover the data. It was all stored on the internal memory. The phone isn't detected when connected to a number of different Windows and one Mac device via USB, no matter what buttons are pressed or if the fingerprint scanner is used as if it was booting normally 'behind' the black screen.

This is what's been tried so far:
-Boot into recovery mode (power+volume down), no apparent change.
-Removing battery and rebooting, no change.
-Removing battery and holding power button for 60+ seconds before returning battery and rebooting, no change.
-Charging for 24+ hours, no change.
-Battery switched for one from my own phone. No change.
-Screen replaced. Issue presented exactly the same afterwards, original screen reconnected.

Can anyone think of any other ideas to get at the data? From the looks of the motherboard the internal flash memory isn't removable, but I'm open to other ideas. The phone does not have to survive the process. I have another V20 available for parts swapping but it's my own main device and so I have to end up with at least one functioning V20 worth of components.
 
Wish I could provide you with assistance but Im mot familiar with LG20's but it sounds like a hardware issue. Your Pc/Mac dose not recognized the device make it all the worse. I can speak from personal experience with a Note 4 softbrick that I spent hours and hourse and hours..... trying to fix. I spent more time that the phone was worth, not to mention all the frustration. A few years later in trying to assist a fellIw Note 4 memer on XDA, I came across a .no-verity-opt-encrypt.zip 6.1 and provided ithe link in the post. Afterwards, I decided to flash it to my old Note via TWRP. I now have 3 working Note 4's lol.
